Narrative
Landowner has "depopulated" plan to 3 houses, 2400 head finishers and requested plan revision
accordingly. All field rates "grandfathered" in, but adjustments made for WA determination. Field #15 is
Dunbar and Gritney soils, but used lower rate (Dunbar) as general soil type and kept the 5.3 ton/ac. yield
from old plan.

The Irrigation Application Factors for each field in this plan are shown in the following table.
Infiltration rate varies with soils. If applying waste nutrients through an irrigation system, you must apply
at a rate that will not result in runoff. This table provides the maximum application rate per hour that may
be applied to each field selected to receive wastewater. It also lists the maximum application amount that
each field may receive in any one application event.

The following Lagoon Sludge Nitrogen Utilization table provides an estimate of the number of acres needed for
sludge utilization for the indicated accumulation period. These estimates are based on average nitrogen
concentrations for each source, the number of animals in the facility and the plant available nitrogen application
rates shown in the second column.
Lagoon sludge contains nutrients and organic matter remaining after treatment and application of the effluent. At
clean out, this material must be utilized for crop production and applied at agronomic rates. In most cases, the
priority nutrient is nitrogen but other nutrients including phosphorous, copper and zinc can also be limiting. Since
nutrient levels are generally very high, application of sludge must be carefully applied.
Sites must first be evaluated for their suitability for sludge application. Ideally, effluent spray fields should not be
used for sludge application. If this is not possible, care should be taken not to load effluent application fields with
high amounts of copper and zinc so that additional effluent cannot be applied. On sites vulnerable to surface water
moving to streams and lakes, phosphorous is a concern. Soils containing very high phosphorous levels may also be
a concern.

The Available Waste Storage Capacity table provides an estimate of the number of days of storage
capacity available at the end of each month of the plan. Available storage capacity is calculated as the
design storage capacity in days minus the number of days of net storage volume accumulated. The start
date is a value entered by the user and is defined as the date prior to applying nutrients to the first crop in
the plan at which storage volume in the lagoon or holding pond is equal to zero.
Available storage capacity should be greater than or equal to zero and less than or equal to the design
storage capacity of the facility. If the available storage capacity is greater than the design storage
capacity, this indicates that the plan calls for the application of nutrients that have not yet accumulated. If
available storage capacity is negative, the estimated volume of accumulated waste exceeds the design
storage volume of the structure. Either of these situations indicates that the planned application interval
in the waste utilization plan is inconsistent with the structure's temporary storage capacity.

Required Specifications For Animal Waste Management
1. Animal waste shall not reach surface waters of the state by runoff, drift,
manmade conveyances, direct application, or direct discharge during
operation or land application. Any discharge of waste that reaches
surface water is prohibited.
2.
There must be documentation in the design folder that the producer
either owns or has an agreement for use of adequate land on which to
properly apply. the waste. If the producer does not own adequate land to
properly dispose of the waste, he/she shall provide evidence of an
agreement with a landowner, who is within a reasonable proximity,
allowing him/her the use of the land for waste application. It is the
responsibility of the owner of the waste production facility to secure an
update of the Nutrient Management Plan when there is a change in the
operation, increase in the number of animals, method of application,
receiving crop type, or available land.
3. Animal waste shall be applied to meet, but not exceed, the nitrogen needs
for realistic crop yields based upon soil type, available moisture, historical
data, climatic conditions, and level of management, unless there are.
regulations that restrict the rate of applications for other nutrients.
4. Animal waste shall be applied to land eroding less than 5 tons per acre
per year. Waste may be applied to land eroding at more than 5 tons per
acre per year but less than 10 tons per acre per year provided grass filter
strips are installed where runoff leaves the field (see USDA, NRCS Field
Office Technical Guide Standard 393 - Filter Strips).
5. Odors can be reduced by injecting the waste or by disking after waste
application. Waste should not be applied when there is danger of drift
from the land application field.
6. When animal waste is to be applied on acres subject to flooding, waste
will be soil incorporated on conventionally tilled cropland. When waste is
applied to conservation tilled crops or grassland, the waste may be
broadcast provided the application does not occur during a season prone
to flooding (see "Weather and Climate in North Carolina" for guidance).
7. Liquid waste shall be applied at rates not to exceed the soil infiltration
--------------------------------------------------------------------------------------------------------------------------------- ------
527557 Database Version 1.06 Date Printed: 01-23-2001 Specification Page 1

10
rate such that runoff does not occur offsite or to surface waters and in a
method which does not cause drift from the site during application. No
ponding should occur in order to control odor and flies.
8. Animal waste shall not be applied to saturated soils, during rainfall
events, or when the soil surface is frozen.
Animal waste shall be applied on actively growing crops in such a manner
that the crop is not covered with waste to a depth that would inhibit
growth. The potential for salt damage from animal waste should also be
considered.
10 Nutrients from waste shall not be applied in fall or winter for spring
planted crops.on soils with a high potential for leaching. Waste/nutrient
loading rates on these soils should be held to a minimum and a suitable
winter cover crop planted to take up released nutrients. Waste shall not
be applied more than 30 days prior to planting of the crop or forages
breaking dormancy.
11. Any new swine facility sited on or after October 1,1995 shall comply with
the following: The outer perimeter of the land area onto which waste is
applied from a lagoon that is a component of a swine farm shall be at
least 50 feet from any residential property boundary and canal. Animal
waste, other than swine waste from facilities sited on or after October 1,
1995, shall not be applied closer that 25 feet to perennial waters.
12. Animal waste shall not be applied closer than 100 feet to wells.
13. Animal waste shall not be applied closer than 200 feet of dwellings other
than those owned by the landowner.
14. Waste shall be applied in a manner not to reach other property and
public right-of-ways.
15. Animal waste shall not be discharged into surface waters, drainageways,
or wetlands by a discharge or by over -spraying. Animal waste may be
applied to prior converted cropland provided the fields have been
approved as a land application site by a "technical specialist". Animal
waste shall not be applied on grassed waterways that discharge directly
into water courses, and on other grassed waterways, waste shall be
---------------------------------------------------------------------------------------------------------------------- - -- - -
527557 Database Version 1.06 Date Printed: 01-23-2001 Specification Page 2

I
applied at agronomic rates in a manner that causes no runoff or drift
from the site.
16. Domestic and industrial waste from washdown facilities, showers, toilets,
sinks, etc., shall not be discharged into the animal waste management
system.
17. A protective cover of appropriate vegetation will be established on all
disturbed areas (lagoon embankments, berms, pipe runs, etc.). Areas
shall be fenced, as necessary, to protect the vegetation. Vegetation such
as trees, shrubs, and other woody species, etc., are limited to areas where
considered appropriate. Lagoon areas should be kept mowed and
accessible. Berms and structures should be inspected regularly for
evidence of erosion, leakage, or discharge.
18. If animal production at the facility is to be suspended or terminated, the
owner is responsible for obtaining and implementing a "closure plan"
which will eliminate the possibility of an illegal discharge, pollution, and
erosion.
19. Waste handling structures, piping, pumps, reels, etc., should be inspected
on a regular basis to prevent breakdowns, leaks, and spills. A regular
maintenance checklist should be kept on site.
20. Animal waste can be used in a rotation that includes vegetables and other
crops for direct human consumption. However, if animal waste is used
on crops for direct human consumption, it should only be applied
pre -plant with no further applications of animal waste during the crop
season.
21. Highly visible markers shall be installed to mark the top and bottom
elevations of the temporary storage (pumping volume) of all waste
treatment lagoons. Pumping shall be managed to maintain the liquid
level between the markers. A marker will be required to mark the
maximum storage volume for waste storage ponds.
22. Waste shall be tested within 60 days of utilization and soil shall be tested
at least annually at crop sites where waste products are applied. Nitrogen
shall be the rate -determining nutrient, unless other restrictions require

12-
waste to be applied based on other nutrients, resulting in a lower
application rate than a nitrogen based rate. Zinc and copper levels in the
soils shall be monitored and alternative crop sites shall be used when
these metals approach excessive levels. pH shall be adjusted and
maintained for optimum crop production. Soil and waste analysis
records shall be kept for a minimum of five years. Poultry dry waste
maintainedapplication records shall be a minimum of three years.
Waste application records for all other waste shall be maintained for a
minimum of five years.
23. Dead animals will be disposed of in a manner that meets North Carolina
regulations.

Crop Notes
The following crop note applies to field(s): 12, 15, 8
Bermudagrass Coastal Plain, Mineral Soil, Poorly Drained to Somewhat Poorly Drained.
Adaptation: Effective artificial drainage MUST be in place to achieve Realistic Yield Expectations
provided for these soils.
In the Coastal Plain, hybrid bermudagrass sprigs can be plante&M- ar. 1 to Mar. 31- Cover sprigs 1" to 3"
deep (1.5" optimal). Sprigs should be planted quickly after digging and not allowed to dry in sun and
wind. For Coastal and Tifton 78 plant at least 10 bu/ac in 3' rows, spaced 2' to 3' in the row. Generally a
rate of 30 bu/ac is satisfactory to produce full groundcover in one or two years under good growing
conditions. Tifton 44 spreads slowly, so use at least 40 bu/ac in 1.5' to 2' rows spaced l' to 1.5' in row.
For broadcast/disked-in sprigs use about 60 bu/ac. Soil test for the amounts of lime, phosphorus,
potassium and micronutrients to apply preplant and for annual maintenance. Apply 60 to 100 lb/ac N in
the establishment year in split applications -in April and July. For established stands apply 180 to 240
lb/ac N annually in split applications, usually in April and following the first and second hay cuts.
Reduce N rates by 25% for grazing. Refer to NCSU Technical Bulletin 305 Production and Utilization of
Pastures and Forages in North Carolina for more information or consult your regional agronomist or
extension agent for assistance.
The following crop note applies to field(s): 12, 15, 8
Cereal/Annual Rye Overseeded — Hay
CEREAL RYE
The cereal rye should be planted by October 15 to provide the best opportunity to get winter growth. The
most consistent stands are obtained from drilling rye into short (less than 3 inches tall) bermudagrass sod.
If drilling is not possible, the seeds may be broadcast on short bermuda sod followed by a light cultivation
with a disc or tillage implement. The seeding rate for broadcast planting of seeds should be 1.5 times the
rate for drilled seeds. The last application of animal waste is to be applied to the bermuda prior to August
31. An application of 50 lbs/acre of Plant Available N (PAN) may be applied between September 15 and
October 30. An additional 501bs.acre of PAN may be applied in February -March. If rye growth is
harvested on time and does not significantly shade the bermuda, PAN rates for the subsequent Bermuda
crop are based on realistic -yields of bermuda. A harvest is required prior to heading or April 7, which
ever comes first. This is necessary to minimize the potential for shading bermuda and reducing its yields.
ANNUAL RYEGRASS
Annual ry-egrass should be planted by October 15 to provide the best opportunity to get winter growth.
The most consistent stands are obtained from drilling ryegrass into short (less than 3 inches tall)
bermudagrass sod. If drilling is not possible, the seeds may be broadcast on short bermuda sod followed
by a light cultivation with a disc or tillage implement. The seeding rate for broadcast planting of seeds
should be 1.5 times the rate for drilled seeds. The last application of animal waste is to be applied to the
bermuda prior to August 31. An application of 501bs/acre of PAN may be applied between September
15 and October 30. An additional 501bs. acre of PAN may be applied in February-March..If additional
PAN is applied to the-ryegrass in April -May, the PAN rate for the bermuda must be reduced by a
------------------------------------------------------------------------------------------- --
527557 Database Version 1.06 Date Printed: 01-23-2001 Crop Note Page 1

corresponding amount. This is necessary because ryegrass growth during April -May will reduce
bermuda yields and shorten the time bermuda can fully utilize the N. A harvest is required by heading or
April 7, which ever comes first to prevent shading of emerging bermuda during April -May period. To
favor the production of the bermuda, additional harvests of ryegrass will be required when the ryegrass
canopy reaches 12 to 15 inches height.
The following crop note applies to field(s): 14, 6
Bermudagrass Coastal Plain, Mineral Soil, Poorly Drained to Somewhat Poorly Drained.
Adaptation: Effective artificial drainage MUST be in place to achieve Realistic Yield Expectations

conditions. Tifton 44 spreads slowly, so use at least 40 bu/ac in 1.5' to 2' rows spaced l' to 1.5' in row.
For broadcast/disked-in sprigs use about 60 bu/ac. Soil test for the amounts of lime, phosphorus,
potassium and micronutrients to apply preplant and for annual maintenance. Apply 60 to 1001b/ac N in
the establishment year in split applications in April and July. For established stands apply 180 to 240
lb/ac N annually in split applications, usually in April and following the first and second hay cuts. Reduce
N rates by 25% for grazing. Refer to NCSU Technical Bulletin 305 Production and Utilization of

Updated Crop Management Practices for Bermuda Winter Overseed
This document, as approved by the Interagency Nutrient Management Committee on
October 10, 2017, hereby modified the July 13, 1998 Memorandum "Crop Management
Practices for Select Forages Used in Waste Management". This modification updates
the application window protocol for the 100 lb Nitrogen PAN rate for both Cereal Rye
and Annual Ryegrass, as well as winter small grains.
• Farms utilizing the 100 lbs./ac PAN rate for the overseed are allowed to apply no
more than 50 lbs./ac PAN from October 1 through December 31 and no more than
50 lbs./ac PAN from January 1 through March 31.
• Applications made during the months of December and January cannot exceed the
combined total of 25 lbs./ac PAN for the two -month period.
• The last application of animal waste is to be applied to the bermuda crop prior to
September 30.
• The PAN rate for grazed systems must be reduced by 25%.
All other requirements of the July 13, 1998 Memorandum continue to apply. Those
requirements include but are not limited to:
Cereal rye and annual ryegrass should be planted by October 15 to provide the best
opportunity to get winter growth.
A harvest is required prior to heading or April 7, whichever comes first, for both
cereal rye and annual ryegrass. This is necessary to minimize the potential for
shading of emerging bermuda and reducing its yield. To favor the production of
bermuda, additional harvest of annual ryegrass will be required when the ryegrass
canopy reaches 12-15 inches height.
These management requirements shall also apply to overseeded winter small grain.

�, «R Mortality Management Methods
/1iG Indicate which method(s) will be implemented.
I e a(rl When selecting multiple methods indicate a primary versus secondary option.
j Iles� Methods other than those listed must be approved by the State Veterinarian.
Primary Secondary Routine Mortality
Burial three feet beneath the surface of the ground within 24 hours of knowledge of animal
a uric mus a atTeast 300 ee�from any owing stream or public y o water ea
(G.S.106-403). The bottom of the burial pit should be at least one foot above the seasonal
high water table. Attach burial location map and plan.
El 1:1 Landfill at municipal solid waste facility permitted by NC DEQ under GS 15A NCAC
13B .0200.
Rendering ata rendering plant licensed under G.S. 106-168.7.
Complete incineration according to 02 NCAC 52C .0102.-
Q A composting system approved and permitted by the NC Department of Agriculture & Con-
sumer Services Veterinary Division (attach copy of permit). If compost is distributed off -fame,
additional requirements must be met and a permit is required from NC DEQ.
In the case of dead poultry only, placing in a disposal pit of a size and design approved by the
NC Department of Agriculture & Consumer Services (G.S. 106-549.70).
❑ a Any method which, in the professional opinion of the State Veterinarian, would make possible
the salvage of part of a dead animal's value without endangering human or animal health.
(Written approval by the State Veterinarian must be attached).
Mass Mortality Plan
Mass mortality plans are required for farms covered by an NPDES permit. These plans are
also recommended for all animal operations. This plan outlines farm -specific mortality man-
agement methods to be used for mass mortality. The NCDA&CS Veterinary Division sup-
ports a variety of emergency mortality disposal options; contact the Division for guidance.
• A catastrophic mortality disposal plan is part of the facility's CAWMP and is activated
When numbers of dead animals exceed normal mortality rates as specified by the State
Veterinarian.
• Burial must be done in accordance with NC General Statutes and NCDA&CZ; Veterinary
Division regulations and guidance.
• Mass burial sites are subject to additional permit conditions (refer to facility's animal
waste management system permit).
• In the event of imminent threat of a disease emergency, the State Veterinarian may enact
additional temporary procedures or measures for disposal according to G.S. 106-399.4.

This plan will be implemented in the event that wastes from your operation are leaking,
overflowing, or running off site. You should not wait until wastes reach surface waters or leave
your property to consider that you have a problem. You should make every effort to ensure that
this does not happen. This plan should be posted in an accessible location for all employees at
the facility. The following are some action items you should take.
1. Stop the release of wastes. Depending on the situation, this may or may not be possible.
Suggested responses to some possible problems are listed below.
a. Lagoon overflow -possible solutions are:
1) Add soil to berm to increase elevation of dam.
2) Pump wastes to fields at an acceptable rate.
3) Stop all flows to the lagoon immediately.
4) Call a pumping contractor.
5) Make sure no surface water is entering lagoon.
b. Runoff from waste application field-actions-inelude:
1) Immediately stop waste application.
2) Create a temporary diversion to contain waste.
3) Incorporate waste to reduce runoff.
4) Evaluate and eliminate the reason(s) that caused the runoff.
5) Evaluate the application rates for the fields where runoff occurred.
c. Leakage from the waste pipes and sprinklers -action include:
1) Stop recycle pump.
2) Stop irrigation pump.
3) Close valves to eliminate further discharge.
4) Repair all leaks prior to restarting pumps.
November 23, 2016

d. Leakage from flush systems, houses, solid separators -action include:
1) Stop recycle pump.
2) Stop irrigation pump.
3) Make sure no siphon occurs.
4) Stop all flows in the house, flush systems, or solid separators.
5) Repair all leaks prior to restarting pumps.
e. Leakage from base or sidewall of lagoon. Often this is seepage as opposed to flowing
leaps- possible action:
1) Dig a small sump or ditch away from the embankment to catch all seepage, put in
a submersible pump, and pump back to lagoon.
2) If holes are caused by burrowing animals, trap or remove animals and fill holes
and compact with a clay type soil.
3) Have a professional evaluate the condition of the side walls and lagoon bottom as
soon as possible.
2. Assess the extent of the spill and note any obvious damages.
a. Did the waste reach any surface waters?
b. Approximately how much was released and for what duration?
c. Any damage noted, such as employee injury, fish kills, or property damage?
d. Did the spill leave the property?
e. Does the spill have the potential to reach surface waters?
f. Could a future rain event cause the spill to reach surface waters?
g. Are potable water wells in danger (either on or off of the property)?
h. How much reached surface waters?
3. Contact appropriate agent es.
a. During normal business hours, call your DMZ. regional office, phone number:
C [d `q,_B-3,3tPAfter hours, emergency number: 1-800-858-0368. Your phone call
should include: your name, facility, telephone number, the details of the incident from
item 2 above, the exact location of the facility, the location or direction of movement
of the spill, weather and wind conditions. The corrective measures that have been
under taken, and the seriousness of the situation.
b. If spill leaves property or enters surface waters, call local EMS, phone number:

System Calibration
Information presented in manufacturer's charts are based on average operation
conditions with relatively new equipment. Discharge rates and application rates change
over time as equipment gets older and components wear. In particular, pump wear tends
to r-eduGe operati _ , - - - - _! and flow. With continued use, nozzle wear results in an
increase in the nozzle opening which will increase the discharge rate while decreasing the
wetted diameter.
You should be aware that operating the system differently than assumed in the design will
alter the application rate, diameter of coverage, and subsequently the application
uniformity. For example, operating the system with excessive pressure results in smaller
droplets, greater potential for drift, and accelerates wear of the sprinkler nozzle. Clogging
of nozzles can result in pressure increase. Plugged intakes or crystallization of mainlines
will reduce operating pressure. Operating below design pressure greatly reduces the
coverage diameter and application uniformity.
For the above reason, you should calibrate your equipment on a regular basis to ensure
proper application rates and uniformity. Calibration at least once every three years is
recommended. Calibration involves collecting and measuring flow at several locations in
the application area. Any number -of containers can be used to collect flow and
determine the application rate. Rain gauges work best because they already have a
graduated scale from which to read the application amount without having to perform
additional calculations. However, pans, plastic buckets, jars, or anything with a uniform
opening and cross-section can be used provided the liquid collected can be easily
transferred to a scaled container for measuring.
For stationary sprinklers, collection containers should be located randomly throughout the
application area at several distances from sprinklers. For traveling guns, sprinklers
should be located along a transect perpendicular to the direction of pull. Set out
collection containers 25 feet apart along the transect on both sides of the gun cart. You
should compute the average application rate for all nonuniformity of the application. On a
windless day, variation between containers of more than 30 percent is cause for concern.
You should contact your irrigation dealer or technical specialist for assistance.

OPERATION & MAINTENANCE PLAN
Proper lagoon management should be a year-round priority. It is especially important to manage
levels so that you do not have problems during extended rainy and wet periods.
Maximum storage capacity should be available in the lagoon for periods when the receiving crop is
dormant (such as wintertime for bermudagrass) or when there are extended rainy spells such as a
thunderstorm season in the summertime. This means that at the first sign of plant growth in the
later winter / early spring, irrigation according to a farm waste management plan should be done
whenever the land in dry enough to receive lagoon liquid. This will make storage space available in
the lagoon for future wet periods. In the late summer / early fall the lagoon should be pumped down
to the low marker (see Figure 2-1) to allow for winter storage. Every effort should be made to
maintain the lagoon close to the minimum liquid level as long as the weather and waste utilization
plan will allow it.
Waiting until the lagoon has reached its maximum storage capacity before starting to irrigated does
not leave room for storing excess water during extended wet periods. Overflow from the lagoon for
any reason except a 25-year, 24-hour storm is a violation of state law and subject to penalty action.
The routine maintenance of a lagoon involves the following:
Maintenance of a vegetative cover for the dam. Fescue or common bermudagrass
are the most common vegetative covers. The vegetation should be fertilized each
year, if needed, to maintain a vigorous stand. The amount of fertilized applied
should be based on a soils test, but in the event that it is not practical to obtain a
soils test each year, the lagoon embankment and surrounding areas should be
fertilized with 800 pounds per acre of 10-10-10, or equivalent
Brush and trees on the embankment must be controlled. This may be done by
mowing, spraying, grazing, chopping, or a combination of these practices. This
should be done at least once a year and possibly twice in years that weather
conditions are favorable for heavy vegetative growth.
NOTE: If vegetation is controlled by spraying, the herbicide must not be allowed to enter the lagoon
water. Such chemicals could harm the bacteria in the lagoon that are treating the waste.
Maintenance inspections of the entire lagoon should be made during the initial filling of the lagoon
and at least monthly and after major rainfall and storm events. Items to be checked should include,
as a minimum, the following:
Waste Inlet Pipes, Recycling Pipes, and Overflow Pipes — look for:
1. separation of joints
2. cracks or breaks
3. accumulation of salts or minerals
4. overall condition of pipes
2

Lagoon surface -- look for:
1. undesirable vegetative growth
2. floating or lodged debris
Embankment -- look for:
1. settlement, cracking, or "jug" holes
2. elope stability — s
3. wet or damp areas on the back slope
4. erosion due to lack or vegetation or as a result of wave action
5. rodent damage
Larger lagoons may be subject to liner damage due to wave action caused by strong
winds. These waves can erode the lagoon sidewalls, thereby weakening the lagoon dam.
A good stand of vegetation will reduce the potential damage caused by wave action. If
wave action causes serious damage to a lagoon sidewall, baffles in the lagoon may be
used to reduce the wave impacts.
Any of these features could lead to erosion and weakening of the dam. If your lagoon
has any of these features, you should call an appropriate expert familiar with design and
construction of waste lagoons. You may need to provide a temporary fix if there is a
threat of a waste discharge. However, a permanent solution should be reviewed by the
technical expert. Any digging into a lagoon dam with heavy equipment is a serious
undertaking with potentially serious consequences and should not be conducted unless
recommended by an appropriate technical expert.
Transfer Pumps — check for proper operation of:
1. recycling pumps
2. irrigation pumps
Check for leaks, loose fittings, and overall pump operation. An unusually loud or grinding
noise, or a large amount of vibration, may indicate that the pump is in need of repair or
replacement.
NOTE: Pumping systems should be inspected and operated frequently enough so that
you are not completely "surprised" by equipment failure. You should perform your
pumping system maintenance at a time when your lagoon is at its low level. This will
allow some safety time should major repairs be required. Having a nearly full lagoon is
not the time to think about switching, repairing, or borrowing pumps. Probably, if your
lagoon is full, your neighbor's lagoon is full also. You should consider maintaining an
inventory of spare parts or pumps.
• Surface water diversion features are designed to cant' all surface drainage
waters (such as rainfall runoff, roof drainage, gutter outlets, and parking lot
runoff) away from your lagoon and other waste treatment or storage
structures. The only water that should be coming from your lagoon is that
which comes from your flushing (washing) system pipes and the rainfall that
hits the lagoon directly. You should inspect your diversion system for the
following:
1. adequate vegetation
2. diversion capacity
3. ridge berm height

Identified problems should be corrected promptly. It is advisable to inspect your system
during or immediately following a heavy rain. If technical assistance is needed to
determine proper solutions, consult with appropriate experts.
You should record the level of the lagoon just prior to when rain is predicted, and then
record the level again 4 to 6 hours after the rain (assumes there is no pumping). This will
give you an idea of how much your lagoon level will rise with a certain rainfall amount
(you must also be recording your rainfall for this to work). Knowing this should help in
planning irrigation applications and storage. If your lagoon rises excessively, you may
have an overflow problem from a surface water diversion or there may be seepage into
the lagoon from the surrounding land.
Lagoon Operation
Startup:
1. Immediately after construction establish a complete sod cover on bare soil
surfaces to avoid erosion.
2. Fill new lagoon design treatment volume at least half full of water before waste
loading begins, taking care not to erode lining or bank slopes.
3. Drainpipes into the lagoon should have a flexible pipe extender on the end of the
pipe to discharge near the bottom of the lagoon during initial filling or another
means of slowing the incoming water to avoid erosion of the lining.
4. When possible, begin loading new lagoons in the spring to maximize bacterial
establishment (due to warmer weather).
5. It is recommended that a new lagoon be seeded with sludge from a healthy
working swine lagoon in the amount of 0.25 percent of the full lagoon liquid
volume. This seeding should occur at least two weeks prior to the addition of
wastewater.
6. Maintain a periodic check on the lagoon liquid pH. If the pH falls below 7.0, add
agricultural lime at the rate of 1 pound per 1000 cubic feet of lagoon liquid volume
until the pH rises above 7.0. Optimum lagoon liquid pH is between 7.5 and 8.0.
7. A dark color, lack of bubbling, and excessive odor signals inadequate biological
activity. Consultation with a technical specialist is recommended if these
conditions occur for prolonged periods, especially during the warm season.
Loading:
The more frequently and regularly that wastewater is added to a lagoon, the better the
lagoon will function. Flush systems that wash waste into the lagoon several times daily
are optimum for treatment. Pit recharge systems, in which one or more buildings are
drained and recharged each day, also work well.

•
Practice water conservation — minimize building water usage and spillage from
leaking waterers, broken pipes and washdown through proper maintenance and water
conservation.
Minimize feed wastage and spillage by keeping feeders adjusted. This will reduce the
amount of solids entering the lagoon. —
Management:
• Maintain lagoon liquid level between the permanent storage level and the full
temporary storage level.
• Place visible markers or stakes on the lagoon bank to show the minimum liquid level
and the maximum liquid level. (Figure 2-1).
• Start irrigating at the earliest possible date in the spring based on nutrient
requirements and soil moisture so that temporary storage will be maximized for the
summer thunderstorm season. Similarly, irrigate in the late summer / early fall to
provide maximum lagoon storage for the winter.
• The lagoon liquid level should never be closer than 1 foot to the lowest point of the
dam or embankment.
• Don not pump the lagoon liquid level lower than the permanent storage level unless
you are removing sludge.
• Locate float pump intakes approximately 18 inches underneath the liquid surface and
as far away from the drainpipe inlets as possible.
• Prevent additions of bedding materials, long-stemmed forage or vegetation, molded
feed, plastic syringes, or other foreign materials into the lagoon.
• Frequently remove solids from catch basins at end of confinement houses or
wherever they are installed.
• Maintain strict vegetation, rodent, and varmint control near lagoon edges.
• Do not allow trees or large bushes to grow on lagoon dam or embankment.
• Remove sludge from the lagoon either when the sludge storage capacity is full or
before it fills 50 percent of the permanent storage volume.
• If animal production is to be terminated, the owner is responsible for obtaining and
implementing a closure plan to eliminate the possibility of a pollutant discharge.
Sludge Removal:
Rate of lagoon sludge buildup can be reduced by:
F

• proper lagoon sizing,
• mechanical solids separation of flushed waste,
• gravity settling of flushed waste solids in an appropriately designed basin, or
• minimizing feed wastage and spillage.
Lagoon sludge that is removed annually rather than stored long term will:
• have more nutrients,
• have more odor, and
• require more land to properly use the nutrients.
Removal techniques:
• Hire a custom applicator.
• Mix the sludge and lagoon liquid with a chopper - agitator impeller pump through large -
bore sprinkler irrigation system onto nearby cropland; and soil incorporate.
• Dewater the upper part of lagoon by irrigation onto nearby cropland or forageland; mix
remaining sludge; pump into liquid sludge applicator; haul and spread onto cropland or
forageland; and soil incorporate.
• Dewater the upper part of lagoon by irrigation onto nearby cropland or forageland;
dredge sludge from lagoon with dragline or sludge barge; berm an area beside lagoon
to receive the sludge so that liquids can drain back into lagoon; allow sludge to
dewater, haul and spread with manure spreader onto cropland or forageland; and soil
incorporate.
Regardless of the method, you must have the sludge material analyzed for waste
constituents just as you would your lagoon water. The sludge will contain different
nutrient and metal values from the liquid. The application of the sludge to fields will be
limited by these nutrients as well as any previous waste applications to that field and crop
requirement. Waste application rates will be discussed in detail in Chapter 3.
When removing sludge, you must also pay attention to the liner to prevent damage.
Close attention by the pumper or drag -line operator will ensure that the lagoon liner
remains intact. If you see soil material or the synthetic liner material being disturbed, you
should stop the activity immediately and not resume until you are sure that the sludge can
be removed without liner injury. If the liner is damaged it must be repaired as soon as
possible.
Sludge removed from the lagoon has a much higher phosphorus and heavy metal content
than liquid. Because of this it should probably be applied to land with low phosphorus and
metal levels, as indicated by a soil test, and incorporated to reduce the chance of erosion.
Note that if the sludge is applied to fields with very high soil -test phosphors, it should be
applied only at rates equal to the crop removal of phosphorus. As with other wastes,
always have your lagoon sludge analyzed for its nutrient value.

The application of sludge will increase the amount of odor at the waste application site.
Extra precaution should be used to observe the wind direction and other conditions which
could increase the concern of neighbors.
Possible Causes of Lagoon Failure
Lagoon failures result in the unplanned discharge of wastewater from the structure.
Types of failures include leakage through the bottom or sides, overtopping, and breach of
the dam. Assuming proper design and construction, the owner has the responsibility for
ensuring structure safety. Items which may lead to lagoon failures include:
• Modification of the lagoon structure -- an example is the placement of a pipe in the dam
without proper design and construction. (Consult an expert in lagoon design before
placing any pipes in dams.)
• Lagoon liquid levels — high levels are a safety risk.
• Failure to inspect and maintain the dam.
• Excess surface water flowing into the lagoon.
• Liner integrity — protect from inlet pipe scouring, damage during sludge removal, or
rupture from lowering lagoon liquid level below groundwater table.
NOTE: If lagoon water is allowed to overtop the dam, the moving water will soon cause
gullies to form in the dam. Once this damage starts, it can quickly cause a large
discharge of wastewater and possible dam failure.
